The ADMV1455 is a highly integrated microwave downconverter optimized for wideband radio designs operating in the 17.7GHz to 55GHz RF range. It can be used as a smaller alternative to larger multichip implementations, allowing for reduced size, weight, and power at the system level.
The ADMV1455 has an integrated local oscillator (LO) signal chain, that accepts LO input signals in the 8.85GHz to 27.5GHz range. Within the LO signal chain are internal amplifiers, a frequency 2× multiplier, a programmable harmonic reject filter, and phase adjust circuitry, which produces the necessary 17.7GHz to 55GHz signal to drive the internal mixer.
The ADMV1455 has two, switch selectable, RF input signal chains. One chain operates within the 17.7GHz to 34GHz range, and the other operates in the 30GHz to 55GHz range. Each chain has multiple stages of low noise amplifiers (LNAs), signal level control, and harmonic filtering. A square law power detector is provided to allow monitoring of the power levels at the mixer inputs.
The ADMV1455 offers single output IF and differential inphase/ quadrature (I/Q) modes of frequency translation. The single output IF mode provides one intermediate frequency (IF) output signal, in the 2GHz to 12GHz range, utilizing the on-chip 90° IF hybrid. The differential I/Q mode provides differential baseband I/Q output signals, from DC to 8GHz.
